Disease as a Larval Mortality Factor in Alfalfa Weevil, \u3ci\u3eHypera Postica\u3c/i\u3e (Coleoptera: Curculionidae) Populations in Illinois [PDF]
, 2017 During the 1974 growing season, larvae of the alfalfa weevil, Hypera postica (Gyllenhal), were examined for pathogens. Three larvae out of 715 examined were infected with a microsporidium.

Protease Production by Species of Entomophthora [PDF]
Applied Microbiology, 1968 Ten insect-pathogenic species of Entomophthora showed wide variation in their ability to produce alkaline protease in surface culture. E. coronata , the most active producer, was selected for studies in submerged culture together with E. virulenta .

Fungal Pathogens Infecting Soybean Aphid and Aphids on Other Crops Grown in Soybean Production Areas of Michigan [PDF]
, 2018 Seasonal prevalence of fungal pathogens infecting soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), was assessed from 2004 to 2006 in two Michigan soybean production areas. In 2005 and 2006 field-collected soybean aphids were incubated, and

Regulation of hyphal growth and sporulation of the insect pathogenic fungus Entomophthora thripidum in vitro [PDF]
, 2016 Entomophthora thripidum is an obligate biotrophic insect pathogenic fungus that grows as protoplasts within the hemocoel of thrips. Prior to penetration through the insect cuticle and spore formation at the insect surface the protoplasts switch to hyphal

Natural Enemies of Alfalfa Weevil, \u3ci\u3eHypera Postica\u3c/i\u3e (Coleoptera: Curculionidae), in Minnesota [PDF]
, 2017 Alfalfa weevil, Hypera postica, is present throughout Minnesota. How- ever, economically damaging populations seldom occur, due to a combination of natural enemies and adverse climatic conditions.

Aeromycology: studies of fungi in aeroplankton [PDF]
, 2014 Air is a natural environment for spores of many genera and species of fungi. Despite its small size and a significant dispersion they have a great impact on human health and different areas of our activities, such as agricultural production. The study on

Infection of cereal aphids by the fungus Entomophthora
Annals of Applied Biology, 1973 SUMMARYThree species of Entomophthora killed many Metopolophium dirhodum, M. festucae and Sitobion avenae on wheat at Harpenden, Hertfordshire, in 1971. Rainfall was low and aphid numbers were small in May and there was no Entomophthora infection. E. planchoniana first infected M. dirhodum early in June and the percentage of each aphid species infected

Iflaviruses in arthropods: when small is mighty
Insect Science, EarlyView.Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.
